Sinds vrijdagavond krijg ik mijn apple mail niet meer gestart op mijn iMac (10.10.5).
's ochtend bij het aanzetten nog wel, maar ;'s avonds reageerde deze niet meer.
Bij het aanklikken springt deze of niet of 1 keer. Mail verschijnt wel bovenin de balk, maar daar kan ik 'voorkeuren' of 'voeg account toe' niet aanklikken (grijs). Als ik Accounts aanklik dan krijg ik na verloop van tijd de melding "het voorkeurpaneel internetaccounts kan niet worden geladen'.

Ik heb een aantal opties geprobeerd zoals Launch mail in safe mode, Boot your Mac into safe mode, Remove mail saved state. Dit heeft geen effect.
Remove and rebuild Mail's container echter nog niet

Op mijn MacBook (10.10.5) doet apple mail het wel.
Iemand een idee?

Post eens een Etrecheck rapport, asjeblief.
http://etrecheck.com/#about

Het is trouwens blijkbaar een vaak voorkomend probleem; hier een vrij goed overzicht:
http://boardreader.com/thread/Why_can_I_not_load_Internet_Accounts_pre_6fascjX49b96.html

Schijnt dus een hekele en ingewikkelde materie, maar ik stel eerst een simpele test voor (ik vermoed namelijk een of andere corrupte property list).

Zoek in je user library "com.apple.mail.plist", onthou waar die vandaan komt (directory wellicht ~library>preferences) en verplaats die even naar je desktop.

Herstart. Bij herstart maakt OSX immers een geheel cleane property list aan.
Gaat je Mail nu wel open? Dan mag je die oudere .plist op je desktop naar de vuilbak slepen, en die vuilbak legen.

Lukt het nog niet, lees dan verder:

Hier nog een zéér verhelderend en beknopt artikel, dat nog wat uitgebreider tips geeft:
http://www.needhelp4mac.com/2015/10/troubleshooting-apple-mail-in-os-x-10-11-el-capitan/

Volgens dit artikel heb je wellicht zowel een oudere, gemigreerde User’s Library > Mail > V2 folder, als een nieuwere (El Capitan) User’s Library > Mail > V3 folder.
Dat schijnt Mail in de war te brengen onder El Capitan.

De grote truuk lijkt om al je mail in de User’s Library > Mail > V3 folder onder te brengen, 1 account per keer, as per dit laatste artikel.

En meer:
https://support.apple.com/kb/PH19174?locale=en_US

Ik denk dat Linc Davis op Apple support > discussions de zaken weer nodeloos moeilijk maakt.

Succes!

Thnx,

Ik heb het bestand com.apple.mail.plist naar bureaublad versleep en herstart, maar dat deed niets.

Ik heb nog niet El Capitan, dus alleen folder V2.
het is een heel gepuzzel merk ik, om alles door te spitten.

Ik heb het etrecheck rapport bijgevoegd, daarin staat een crash bij internetaccounts.
